My dad's new wife is so sexy, I can't stand it anymore!! Recently, my dad remarried. My new mother is Maki-san. She's young and beautiful, and I haven't been able to get used to her. To be honest, it's awkward... One night, I heard a strange sound coming from my dad's bedroom. It sounded like something was being knocked. I cautiously peeked in and found the two of them engaged in S&M play. That strict dad is a masochist and the gentle-looking Maki is a sadist... The next morning, Maki-san seduces me, saying, "I actually like being dominated..." Three sexy, shaved mature women captivate their young sons in these three forbidden dramas!!
